This plugin has been tested on Android and Web, and is being made available for testing on iOS. Please consider reporting any bugs you encounter here or submitting pull requests here.

Example

Initialisation:

final player = AudioPlayer();
var duration = await player.setUrl('https://foo.com/bar.mp3');

Standard controls:

player.play();
await player.seek(Duration(seconds: 10));
await player.pause();
await player.stop();

Clipping audio:

await player.setClip(start: Duration(seconds: 10), end: Duration(seconds: 20));
await player.play(); // Waits for playback to finish

Release resources:

await player.dispose();

Catch player error:

player.setUrl("https://s3.amazonaws.com/404-file.mp3").catchError((error) {
  // catch audio error ex: 404 url, wrong url ...
  print(error);
});

Platform specific configuration

Android

If you wish to connect to non-HTTPS URLS, add the following attribute to the application element of your AndroidManifest.xml file:

    <application ... android:usesCleartextTraffic="true">

iOS

If you wish to connect to non-HTTPS URLS, add the following to your Info.plist file:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSAllowsArbitraryLoadsForMedia</key>
    <true/>
</dict>

By default, iOS will mute your app's audio when your phone is switched to silent mode. Depending on the requirements of your app, you can change the default audio session category using AudioPlayer.setIosCategory. For example, if you are writing a media app, Apple recommends that you set the category to AVAudioSessionCategoryPlayback, which you can achieve by adding the following code to your app's initialisation:

AudioPlayer.setIosCategory(IosCategory.playback);

Note: If your app uses a number of different audio plugins in combination, e.g. for audio recording, or text to speech, or background audio, it is possible that those plugins may internally override the setting you choose here. You may consider asking the developer of each other plugin you use to provide a similar method so that you can configure the same audio session category universally across all plugins you use.

MacOS

To allow your MacOS application to access audio files on the Internet, add the following to your DebugProfile.entitlements and Release.entitlements files:

    <key>com.apple.security.network.client</key>
    <true/>

If you wish to connect to non-HTTPS URLS, add the following to your Info.plist file:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSAllowsArbitraryLoadsForMedia</key>
    <true/>
</dict>
